After a brief statement of the goals of energy education, the concept of energy literacy is loosely defined and two ways are identified by which energy education can be introduced into school curricula. A number of related generalizations are identified that might form the basis for the development of energy curricula, followed in each case by a brief list of selected reference materials. These generalizations include lessons that may be taught on: conversion and measurement of energy, energy...

The role of molecular structure in determining biological activity is shown. The correlation of the structure of sulfanilamide with that of a vitamin essential for bacterial growth leads to a more general investigation of the biochemical nature of growth. Paper chromatography is used to separate some of the material found in chromosomes. It is proposed that compounds similar to those found in chromosomes may stop cell division and thus be useful in controlling cancer. The effect and mechanism...

Vanadium is studied as a typical transition element. The different oxidation states of vanadium and the corresponding colors are observed and then identified by means of a quantitative titration of vanadium (II) solution with cerium (IV) solution. The oxidation states and the observed colors are correlated with the electronic structures using an orbital board. The reaction with hydroxide ion and the formation of complex ions containing vanadium in different oxidation states are demonstrated....

A study of the hydrolysis of the ester, methyl benzoate, shows that the discovery of a reaction mechanism includes a determination of the chemical equation, the structures of the reactants and products, the fate of each atom of the reactants, and the structures of the intermediate molecules. The concepts of bond polarity and the effect of varying the structure of the ester also provide valuable hints. The use of oxygen-18 and its detection in a mass spectrometer provide critical experimental...

The relationship between gaseous pressure and molecular collisions is explored. The effects on molecular collisions of varying the number of molecules per unit of volume and of varying the temperature are studied. The experimental study of the relative rates of effusion of hydrogen, oxygen, carbon dioxide and sulfur hexafluoride leads to the quantitative relationship among molecular mass, molecular velocity, and absolute temperature. Mechanical models illustrate the experimental observations....

Observations of two spheres suspended from the terminals of a high voltage generator remind us of the principles that opposite charges attract, like charges repel, and uncharged bodies have no electric interaction. To determine quantitatively the effect of distance on electric force, a sensitive balance measures the force between two charged spheres. The distance is varied and the electric force is calculated from changes in balance readings. A graph of electric force against distance suggests...

Observations are made of electric effects, including deflections of streams of liquids by a charged rod, and changes in charging time of a capacitor. There is evidence that different molecules give two types of results: some give very marked interactions with electric charges, while others give little effect. To explain these different results, a conceptual model is developed based on two types of molecules: polar and non-polar. Consideration of bond polarity and molecular shape allows...

Two methods of measuring ionization energy, photo-ionization, and electron bombardment, are shown. A high vacuum system is used with a simple cell to measure electric conductivity of gases. The photo-ionization of sodium by the use of a mercury light source and a monochromator is carried out. The electron-bombardment method is then demonstrated with sodium and three noble gases. Animation shows what occurs on the atomic level during the ionization process. Ionization energy is defined as the...

Many properties of matter such as fluidity, vaporization and rates of chemical reactions indicate that molecular motion must be occurring and that the freedom of motion increases in going from the solid to the liquid to the gaseous state. The concepts of translational, rotational, and vibrational molecular motions allow the interpretation of the observed properties. The use of animation and dynamic models makes clear how the observed properties depend on the types of motion occurring at the...

This description explains the energy levels and line spectrum of the hydrogen atom and furnishes the basis of contemporary theory of chemical bonding. The electron position in the atom is considered in terms of probability, and the meaning of a 1s orbital is clarified with a digital computer plot, two analogies, and animation. The principal quantum number, n, is introduced together with its relation to energy...

The synthesis of 2-butanone, a ketone, from 2-butanol, an alcohol, as an example of a common type of organic synthesis. Three basic steps are developed: synthesis, purification, identification. In the synthesis, 2-butanol is oxidized by sodium dichromate and sulfuric acid to yield 2-butanone. Purification is accomplished by solvent extraction with ether followed by distillation of the 2-butanone. The identity of the product is established by infrared absorption spectroscopy and then more...

A catalyst is shown to be a substance which speeds a reaction by providing a new reaction mechanism to an already possible reaction. The new mechanism ordinarily has a low activation energy. The catalyst reacts, then is regenerated at a later stage of the mechanism. Science Consultant: Professor Richard E. Powell, University of California, Berkeley. Wardâs Volume 3, CHEM Study #4127, 17 minutes. In color, 1989.

Proton-donor-acceptor theory is used to interpret the experimental behavior of acid-base indicators. Experiments and animation show the effects on indicators of changing acidity. Equilibrium constants of four indicators are determined and the indicators arranged in order of decreasing acid strength. The competition among bases for protons is shown by mixing the indicators and showing that each changes color at different total acidity.

why do we know more today than we did yesterday? One reason is that scientists engage in research. The excitement of discovering new knowledge through research is illustrated by studying the bond strength of gaseous titanium monosulfide. Gaseous TiS molecules as well as gaseous titanium and sulfur atoms are produced by the vaporization of the high melting crystalline titanium monosulfide at temperatures near 2000°K. The procedures for producing and measuring temperatures in this region are...

Nitric acid acts as an acid in the manufacture of chemical fertilizers; it acts as a base in the manufacture of nitro compounds; it acts as an oxidizing agent in many systems. In making the fertilizer ammonium nitrate from nitric acid, it is necessary to neutralize the acidity of HNO3. This is accomplished by addition of NH3. In nitration reactions, such as the making of nitrobenzene, nitric acid is made to act as a base in the presence of sulfuric acid and forms nitronium ion which is the...
